SlicerVMTK fails to build on cdash since a few weeks. The reported errors hint towards an environment problem on the build machines. It builds fine on Arch. Thanks for having a look.
It actually appears like errors about not being compatible with VTK 9.6. When building on Arch did you use VTK 9.6?
See the following for updating details:
At 1b21266bf47, Slicer built with VTK 9.5.
I’ll try a clean build next time. Thanks.
A clean build of Slicer used VTK 9.6.
SlicerVMTK could be built after fixing the <iostream> includes, both in VMTK itself and in the C++ modules of SlicerVMTK.
I’ll send a PR in both projects ASAP.
